10 Differences between SL100 and BC107 BC107 BC107 in that BC stand for Buried Channel 107 is the product version that indicate the how much of matierial and types of material used for manufacture. SL100 SL100 is a general purpose, medium power NPN transistor . It is mostly used as switch in common emitter configuration. The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. This is known as the biasing. 10 Differences between SL100 and BC107 specifications BC107 SL100 Polarity NPN Transistor PNP Transistor No. of pins 3 3 Package To-18 To-39 Collector-Emitter Voltage 45v 50v LEAD CODE: 1) Emitter 2) Base 3) Collector 1) Emitter 2) Base 3) Collector Total power dissipati...
